The DBA 4000 Series slotted front rotor for 2013–2020 Nissan Altima sedans is a direct-replacement rotor cast from XG-150 high-carbon alloyed iron and profiled for thermal stability. DBA’s Kangaroo Paw ventilation increases surface area and cooling efficiency, while the T3 bi-directional slot pattern improves pad bite and gas evacuation. It’s intended to handle repeated heavy braking without compromise.
